Which type of negotiation is defined as interest-based or principled negotiation?

Integrative negotiation is defined as interest-based or principled negotiation because it focuses on mutual interests and collaborative problem-solving rather than merely dividing resources or positions. This approach encourages parties to work together to find solutions that satisfy the interests of all involved, promoting a win-win scenario.

In integrative negotiation, participants prioritize understanding each other's needs and seek creative options for mutual benefit, rather than competing against each other for the biggest slice of a fixed pie. This orientation fosters an environment of trust and cooperation, which is fundamental for achieving sustainable and satisfactory outcomes for all negotiators.

The other types of negotiation mentioned, such as distributive negotiation, typically focus on single-issue scenarios where the goal is to claim the largest piece of the resource, often leading to a win-lose outcome. Cooperative negotiation may share some similarities with integrative negotiation, but it does not necessarily imply a focus on interests or the creation of value, and competitive negotiation emphasizes gaining advantage at the expense of the other party, countering the essence of integrative approaches.
